It's wintertime in New York and Jo is dragging Mac through the streets to make it to an annual window display unveiling at a renowned department store in Manhattan. In the crowd, Mac eyes a pickpocket and gives chase, annoying Jo since she really doesn't want to miss the display. They catch the pickpocket and the display is presented only to reveal a man's dead body among the hung ornaments and gift boxes in the window. The victim, Richard Grossman, was a not-well-liked store manager whose employees despised him. Only one employee, who Grossman fired shortly before his death, had a prior record for assault, Pascal Denton. Denton, who was engaged to another employee Alena Maybrook until six months ago, tells the team he is innocent but is glad Grossman is dead and the team finds his story checks out. The team finds the pickpocket had blood from the scene on his jacket and he tells them a young woman rushing out of the store in a hurry bumped into him. Surveillance footage from the store reveals the woman who bumped into our pickpocket is Alena Maybrook and the blood evidence left in the store's bathroom in linked to her as well. It turns out, Maybrook had recently found out she was dying from cancer and was stealing from the store to try an help a fellow co-worker. Grossman caught her on tape and threatened to expose her if she did not start a sexual relationship with him. Alena reluctantly agreed but that night she stood up to Grossman and said no to his advances. Grossman attacked her but Maybrook was able to get her hands on a metal rod from the display and hit Grossman over the head, killing him.
